STM32MP25 is a new SoC from STMicroelectronics. The machine was pushed by Alexandre [1] in his tree. On this new SoC, the SDMMC peripheral, using PL18x/MMCI driver has been updated to v3. The driver has been updated to manage this new version, and the new features it supports: * FIFO size increased from 64B to 1kB * IDMA size alignment/mask updated * New block gap hardware flow control * Delay block updated and dependent on SoC This series was pushed on top of next branch in Ulf's mmc tree, as it requires feedback clock update patch [2].
